Sony has just officially announced the new LA-EA5 A-Mount to E-Mount Adapter. This new adapter costs $248, first available for pre-order at B&H.
Sony LA-EA5 Overview
The LA-EA5 Adapter enables the use of Sony A-mount lenses on E-mount mirrorless camera bodies, and maintains full lens performance, including AF with SSM, SAM, and even AF lenses without an internal motor, as well as relays in-camera corrective features. Maintaining the functionality of both the lens and the camera, this adapter is tested to support phase-detection autofocus in order to provide Real-time Tracking and Eye AF functions, as well as quick continuous shooting up to 11 fps with AF/AE tracking. AF and AE tracking are even supported with lenses lacking an internal motor when working with the Alpha a7R IV and a6600 cameras. The adapter has no optical components to affect image quality and its fully electronic design also retains Exif data transmission to benefit post-production and file management. Additionally, its sleek cylindrical design is well-suited to camera bodies with an attached vertical grip.
